SPECIFICATION forming part of Letters Patent No. 617,092, dated J anuary 3, 1899.

Application filed February 25,1898- Serial No. 671,674. (No model.)

To ctZZ whom, it may concern.-

Be it known that I, FREDRICK J. FURMAN, of Geneva, in the county of Ontario, in the State of New York, have invented new and useful Improvements in Generators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in generators particularly applicable for heating purposes, and has for its object the production of a simple and practical construction which is economically manufactured and assembled and is highly efficient in use; and to this end it consists in the combination, construction, and arrangement of the component parts of a generator, as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a perspective of my improved generator, the ash-door being shown by dot ted lines. Figs. 2 and 3 are respectively vertical and horizontal sectional views taken on lines 2 2 and 3 3, Fig. 1, the smoke-conduit projecting from the rear section being omitted in Fig. 2. Figs. 4. and 5 are perspective views of the opposite faces of the front section of my improved generator. Fig. 6 is a perspective view of one of the intermediate sections of said generator inclosing the combustion-chamber. Figs. 7 and 8 are perspective views of opposite faces of the section forming the rear wall of the combustion-chamber. Fig. 9 is a perspective view of the section arranged at the rear of the section seen in Figs. 7 and 8. Figs. 10 and 11 are opposite face views of the rear section of my generator.

This improved generator preferably consists of a series of upright sections A A A A A A A, arranged one in advance of the other and preferably constructed so as to form the outer casing or shell of the generator and to inclose its combustion-chamber A ash-pit A heating-chambers, and smokeconduits. The sections A A A A A A A are preferably formed with substantially upright and horizontal fluid-containing chambers a a, alined with each other and provided with fluid-passages a a which generally extend through the front and rear walls of the lower ends of the chambers aand the central portions of the chambers a and receive suitable bolts 13 for securing said sections together. The chambers a, are usually comparatively narrow and extend upwardly from a plane substantially coincident with that of the bottom of the combustion-chamber to a plane above said chamber. It is obvious, however, that the chambers to may extend upwardly from a higher or lower plane, if desired. The chambers a are preferably continuous from end to end, are connected at their opposite extremities to the upper ends of the substantially upright chambers a, and are provided with upwardly-extending central portions a The lower portions of all the chambers a, usually decrease in thickness toward their bottom edges, extend downwardly between the upright chambers a, and communicate with the inner sides of the chambers a, and the lower portions of the chambers a of the sections A A A A are formed with downturned extremities a The opposite faces of the lower portions of the fluidcontaining chambers a of the sections A A A A A and the inner faces of the corresponding portions of the chambers 00' of the sections A A are generally provided with substantially upright corrugations a for presenting a large amount of heating-surface to the products of combustion impinging thereagainst. Said faces of the sections AA A A are also generally provided with projecting lengthwise surfaces charranged one above the other for additionally increasing the heatingsurfaces presented to said products of combustion. It is obvious, however, that the corru-. gations a and the surfaces a may be dispensed with, if desired.

In the preferable construction of my generator the sections A A A A A inclose the combustion-chamber A and the ash-pit A and the sections A A are arranged at the rear of said combustion-chamber and ash-pit.

The fluid-containing chambers a of the sections A A A A A are therefore preferably arranged at opposite sides of the combustionchamber A for forming the side walls thereof, and the lower portions of the chambers a of the sections A A are extended downwardly beneath the corresponding portions of the sec tions A A A for forming the front and rear walls of said chamber A The lower portion of the chamber a of the section A is generally formed thinner than the chambers a of said section in order that its rear face may be somewhat in advance of the corresponding faces of said chambers to. The lower portion of said chamber a is also formed with an opening a which permits the entrance of fuel within the combustion-chamber A and is closed bya suitable door A. The side walls of the sections A A A A A usually extend downwardly beneath their chambers a for inclosing the ash-pit A which may be provided with a suitable inlet-opening a and a door ca The sections A A A A A" are preferably provided wit-h suitable flues A and fire-passages A The fines A generally consist of upwardly-elongated passages, which extend through the front and rear faces of the sections A A A A A from points at opposite sides of the combustion-chamber A to points above said chamber. The fire-passages A extend laterally from the portions of the inner sides of the chambers a of the sections A A A A A forming the upright sides of the combustion-chamber, and communicate at intervals with the inner sides of the fiues A. These fire -passages preferably consist of grooves or cut-outs, which are provided in the adjacent faces of the sections A A A A A are alined with the spaces between the lower portions of the chambers a of said sections, and are usually formed of unequal width, being generally increased gradually in width toward the front end of the combustion-chamber A in order to equalize the draft from all portions of the combustion-chamber.

The sections A A, arranged at the rear of the combustion-chamber A", serve to materially cool the products of combustion before their escape from my improved generator. The substantially upright fluid containing chambers a of these sections A A are usually somewhat narrower than the corresponding chambers of the sections A A A A A and the lower portions of the fluid containing chambers a of the sections A A are extended downwardly to substantially the same plane as the corresponding portion of the chamber a of the section A As previously stated, the lower portions of the chambers a of the sections A A decrease in width togenerally connected by substantially horizontal passages A A in the intermediate and lower portions of the section A The passage A may be closed by a suitable damper A, and the passage A is normally open. The section A is usually provided with a smoke-passage A extending from front to rear therethrough in alinement with the passage A and discharging into a suitable smoke-conduit A From the foregoing description it will be understood that the chambers a a of the sections A A A A A A A constitute the heating-chambers of my improved generator and that the fines A fire-passages A and smokepassages A A A A form the conduits or passages for the products of combustion. The steam or water heated within said heating-chambers escapes through suitable conduits A and is returned to said chambers, together with any additional feed-water, by conduits A which preferably discharge into the lower portion of the chamber CL of the section A. The circulation of the water in my improved generator is particularly positive and effective, as the paths of the water are upright and short and as there is an up-anddown circulation on each side of the combustion-chamber. The products of combustion impinge directly against the lower portions of the chambers a, which presenta large amount of surface to said products of combustion and divide the same into thin sheets for causing a great amount of heat to be imparted to the adjacent water. Said products of combustion are somewhat retarded in their onward movement by the spaces between the lower portions of the chambers a, but finally pass laterally from the combustion-chamber A and said spaces in thin sheets through the firepassages A and into the fines A and smokepassages A whence they escape through the passages A A when the damper A is open or through the passages A A when said damper is closed. There are comparatively few horizontal surfaces in my improved generator for the accumulation of soot, and the products of combustion within said generator are divided into thin sheets, escape at substantially uniform speed from all portions of the combustion-chamber, and before their exit pass along surfaces cooled by the incoming water. The efficiency of said generator is therefore particularly high.

The construction and operation of my improved generator will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be obvious that considerable change may be made in the detail construction and arrangement of the parts of said generator without departing from the spirit of my invention.
